Application filed llareh- 2, was. serial No. 540,474.

To all whom it may concern: Be it known that I, JERRY D. RYAN, a citizenof the United States, residing at Bron son, in the county of Branch andState of Michigan, have invented new and useful Improvements inGenerator and Battery Protective Means, of which the following is aspecification. v The object of my said invention is the provision ofsimple and reliable means for precluding the burning out of electricgenerators and preventing the discharging of storage batteries such asused in the ignition systems of'automobiles.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure1 is an end elevation of a generator and my improvement.

Figures 2 and 3- are enlarged vertical sections taken in the planesindicated by the lines 2-2 and 33,respectively, of Figure 1, A f (IFigure 4 is a diagrammatic view showing the normal arrangement of theimprovement.

Similar numerals of.reference designate corresponding partsjin all ofthe views of the The nerator 1 is grounded at 2 and may be of t eordinary well known construction or of any other construction compatiblewith the urpose of my invention.

e storage battery 3 may be of any aptype, and is grounded at 4.

At 5, re 4, is a terminal grounded at 6, and at 7 is the usual cat-outappurtenant V by a grounded casing to the nerator 1. y

In e present-and preferred embodiment of my invention the terminal 5 isformed connected at 8, to the generator casing an designated by 5 in theAccording to my invention a fuse 8 isinterposed in the electricalconnection between the cut-out 7 and the battery 3, the said fuse 8being arranged transveisely in the casing 5 and terminals 91nsulatedfrom the walls of the casing as'designated by 10 inFigures2and3.

Connected to one wall of/the casing 5 but insulated therefrom asindicated b 11 in Figures 2 and 3 is a'resilient groun ing device 12 onwhich is a conta t 13. The said 'trica-l connection with the casing 5.When,

however, the points of the cut-out 7 stick or the generator overcharges,the fuse 8 will be consumed and will automatically release the hook 14and permit the device 12 to snap into contact with the casing 5, withthe result that the generator will be grounded as designated by 6 inFigure 4 so that the automobile can be operated without injury to thegenerator 1. I

It will also be manifest that when the battery 3 is removed from theautomobile, the hook 14 may be manually disengaged from the fuse 8 toground the generator through the device 12 and the casing 5 whereuponthe car may be operated with lgnition furnished from a magneto withoutinjury to the generator 1.

Ihave entered into a detailed description of the construction andrelative arrangement of the arts embraced in the present and preferredembodiment of my invention in order to impart a full, clear and exactunderstanding of the said embodiment. I do not desire, however, to beunderstood as confining myself to the said specific con-- may be madesuch as fa withinthe scope of claims.

Having descri'bed my invention, what I claim and desire to secure byLetters-Patent, 1s:-

1. In protective means for the purpose set forth, the combination of agenerator, means to electrically connect the nerator and a storagebattery and form in part b a fuse, a grounded terminal, and means eectrically connected with the generator and insulated from said fuse andnormally held .by the fuse awayfrom said grounded terminal and tendingwhenr'eleased to contact with said terminal and thereby ground thegenerator.

2. In protective means for the purpose 5&1 f th, he combination of agenerator.

formed by a casing containing and insulatedfrom the fuse and thelast-named means. 3. In protective means for the purpose set forth, thecombination of a generator, means to electrically connect thegenerator-and a storage battery and formed in part by a fuse,

a grolmded terminal, and means electrically connected with-the generatorand insulated,

from said fuse and normally held by the fuse away from said groundedterminal and tending when released to contact with said terminal andthereby ground the generator; the saidgrounded terminal formed-by acasmg containing and insulated from the 15(1):; normally engaging andheld by the fuse and the last-named means, and the said last-named meansbeing in the 'form of strip on whichis a pivoted insulated 4. In astarting and lighting system for 5 automotive vehicles including agenerator,-

a battery and an automatic cut out between the battery and generator, ofa protecting device for the system when the automatic cut out fails tofunction includ-' ing a fuse wire interposed in the circuit adapted to.burn out when the battery discharges through the "generator and cutout, anda switch for groun the generator normally held in open positionby said fuse wire.

5. In a starting and lighting system'for automotive vehicles including abattery, 2. generator, and an automatic cut out, of a protecting devicefor the system when the cut out fails to function ,including'a fuse wireinterposed between the battery, generator and cut out adapted to burnout when the battery dischargesthrough the cut out and generator, and aswitch for grounding the generator when the fuse wire burns outincluding a movable contact and a stationary contact, the movablecontact being normally held out of engagement with the stationarycontact by said fuse wire;

In testimony whereof, I a'flix my JERRY D. R AK.
